(1) Genuine J201 JFET.

This is one of the most important parts of your build so be sure to get genuine transistors.

Batch tested using a proper JFET circuit tester. Many common circuit testers can have trouble identifying a JFET due to its nature. This is widely known in the electronics field. This is why you should only test in a working circuit or a proper JFET tester used to determine Idss and Vgs. Do not throw out what me be perfectly good JFETs.

This is the testing circuit, and process that I use for all batch testing, and is the only reliable way to test without false, or inaccurate readings.

Customer Satisfaction Reply:

“I usually just grab the SMD’s and use a daughter board. I just wanted to thank you for selling me GOOD through-hole ones.  These are so good I didn’t even socket anything after the first build. I also appreciate you not pricing them like they are made of gold.  Looking forward to doing more business with you moving forward.”
Top Notch Service y’all,
